Added.  You should also be automatically CC'd on anything filed to  
that component,

Hi Richard,

Thanks for working on this! Your patched solved my initial problem,
but introduced another one. Please find attached another BC file that
fails on xcore with the linear scan regalloc.

This is the error message I get
eliminateFrameIndex Frame size too big: -3
0   llc       0x08affd1e
1   libc.so.6 0xb7d35a01 abort + 257
2   llc       0x081a0972
llvm::XCoreRegisterInfo::eliminateFrameIndex(llvm::ilist_iterator<llvm::MachineInstr>,
int, llvm::RegScavenger*) const + 1570
Aborted

Could you check what is still wrong?

-Roman
